Oiled air filters versus dry air filters
I have an AFE stage 2 megacannon with a PG7 and the regular filter. I swap them in and out while cleaning the other. I'm now tired of oiling and cleaning. I want to go to a dry filter but don't know if I should switch to an Amsoil Nano or go with the Pro Dry from AFE. Any comments on how either one will perform in the dust versus the PG7 or why one would be better than the other? Thanks.

My concern with oiled filters is the fact that it is TOO easy to over oil, and even when you don't over oil, the oil mist can contaminate mass air sensors. Happened on my F150, and known to be an issue on VW diesels too.
I've been looking for a dry filter: Just haven't bothered to pull the trigger yet.

Positives
- Quality construction....well made, IMO.
- Good filtration; Zero dust or debris in my intake tubes or turbo throats.
- Very easy to clean. 20-30 psi compressed air on the inside blows them clean. Your back on the road in under 5 min. First of each month, I give it a quick 'blow out' and that's it!
Negatives
- Restrictive above about 400-450 hp. Just not enough flow for my set up.
- Turbos spool a bit slower and I get suction noise (vacume pressure) when playing hard.
I also discovered the PRO Guard 7 costs about 15 hp on my CTD, vs the AFE Racing filter (5 layer). But that's for another thread.
I now use the Amsoil Nanofiber Filter for daily driving and work, which is usually set around 425 hp anyway. Love it! I switch to the AFE Race Filter for dynos, drag strip or weekend playing. At my present rate I figure I will never need to clean/re-oil the AFE filter in this lifetime.

I run a lot of dirt/gravel roads and was also sick of cleaning oiled filters. Last year I bgt an Amsoil Microfiber Filter (#4095) to test against the Pro Guard 7 that came with my BD twins. A brief summary of my findings on the Amsoil Filter...

Thanks for the info guys. It looks as of right now that Amsoil doesn't have a filter that will fit my setup. The only 6" flange they make is way too short for me. It wouldn't flow near as much as my AFE. It looks like I will just go with a BHF if I can find one that will work or go with a Pro Dry from AFE.
